Research on Enhanced Treatment Technique of Ammonia and Nitrogen in Urban Sewage in the Northern Areas

污水中氨氮的处理较为困难,在寒冷地区冬季生物脱氮效果几乎为零。本文从反应机理和影响因素研究入手,探讨低温季节强化处理措施、生物脱氮运行参数,最后确定了处理工艺流程,及其经济分析结果。

In sewage treatment, it is relatively difficult to remove ammonia and nitrogen, and this is true especially in cold areas where, in winter, the effect of biological denitrification comes as near as zero. Starting with the study on reaction mechanism and influence factors, this paper discusses enhanced treatment technique used in low temperature season, analyzes performance parameters of biological denitrification, sets technological process of treatment and also provides the result of economic analysis.
